Question

In this project, we will make up a banking system. You are an employee of MadeUp Banking. Your job is to manage multiple bank accounts. Here, you would create new accounts, deposit to an account, withdraw from an account, delete account, sort the accounts, or do inspection on one or all bank accounts. In order to do this job, you would need the tool for each of those items. The bank maintains a list of accounts. This list has to be available as long as the bank is in business.

Write a program in C++ to run the MadeUp Banking business. As state above, the list of account has to be available as long as you run the program. This means the list of the account has to be initialized in the ​main()​ function. Write a function for each of the items above. You will call these functions to perform any task on the bank accounts. Each account will have account number, name (last, first), and balance. The ​header file​,​ function file​, and ​main file​ are as the sample below. ​All functions are of type ​void​. You will fill in the necessary function parameters.
In order to do this project, you would need to understand ​pointers​, ​functions​, and ​vectors among other basic C++ knowledge. You will follow the exact requirement and format of the program. Any unnecessary changes will result in points taken off.
